APPARATUS FOR CUTTING BUTTER.

T all whom. it may concern:

Be it known that I, ALFRED T. SERRELL, a citizen of the United States ofAmerica, and a resident of Yonkers, New York, have invented certain newand useful Improvements in Apparatus for Cutting Butter, of which thefollowing is a specification.

The object of this invention is to provide a device which is adapted tocut from the ordinary cylinders of butter, cheese, etc., as the sameexist in their incloslng tubs, sectors of desired masses and weights,and for this purpose it consists of two members hinged together at oneof their ends, each member having an edge, ad acent to such hinged end,sharpened to form a cutter, and of an arc-shaped link connected to oneof the said members and to which the other member is adapted to beclamped at var ous points, whereby the sector formed by such members maybe varied, and it further consists in the construction, arrangement andcombination of the several parts of which it is composed as will behereinafter more fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts aredesignated by corresponding marks of reference,--Figure 1 is aperspective view of a device embodying my invention. Fig. 2 is a planview thereof, showing in full lines its application to a tub of butterhaving one diameter, and in dotted lines its application to a tub havinga smaller diameter. Fig. 3 is a section showing the adjustable clamp forthe blade and link. Fig. 4 is a detail of an adjustable connection whichmay be used between the link and the blade by which it is carried.

The two blades A and B are each in the shape of a parallelogram, eachhaving its lower edge, a and b, respectively, sharpened, and areconnected at one of their ends by the pivot pin C, passing throughhinged knuckles formed upon the blades. Each blade is moreover providedwith a suitable U-handle D, by which it may be forced downwardly intothe butter, and removed therefrom. The blade B has projecting from theouter side thereof near its outer end, an ear B preferably formedintegral with the blade by bending the metal of the latter over at itsupper edge, and to such ear is pivoted one end of an arc-shaped link Ewhich has a series of holes e formed therein at intervals, the holesbeing connected by a central slot 6 of less width than the diameter ofthe holes. The blade A has proectmg from its outer side an ear A formedin the same manner as the ear B and having the same relative positionupon the blade- A as the ear B has on the blade B, and through such ear,and through the arced link passes a locking pin F. This pin comprises alower head f, a body portion 1, and a reduced stem portion f having,when the parts are. assembled, a head-washer f' fastened thereon in anysuitable manner as by up-setting the metal of the stem. In the normalposition of the parts, the body portion f is held within a perforationin the ear A, and 1n one of the holes e of the link E by means of aspiral spring G, which encircles the stem portion 7, and is held betweenthe upper face of the link e, and the lower face of the head-washer, thediameter of body portion f being such that it will not pass through theslot e of the link. The blades thus held are fixed in angular relat onto each other. However, upon depressing the pin F, the reduced stem fwill bebrought into the holes a of the link, and as such stem-portionhas a diameter so small as to permit it to pass along the slot 6' in thelink, the blades may be shifted to and from each other and locked in adesired position by again releasing this pin. The arced link is, bypreference, graduated opposite the several holes therein to indicate theweight of the sector of butter, or other commodity, of its respectiveaverage densitv and given thickness, which will be cut by the bladeswhen the pin f is in the corresponding hole. However, to permit correctindication of weight with variable density of material, the arced linkis, by preference formed in two pieces having a sliding length-wiseadjustment upon each other as is shown in Fig. 4, the two pieces beingadapted to be clamped together when adjusted, by means of a clamp-screwH.

Inasmuch as the tubs used for packing butter or cheese vary withincertain limits in diameter, I, by preference, make the length of theblades equal to the diameter of the smallest standard-sized tub withwhich such blades are to be used, as is shown in dotted lines in Fig. 2.With this relation of the parts. the contents of the tub will be cutinto a series of sectors, while if the tub is of greater diameter, theuse of the blades of the slightly less diameter, results I-claixn, anddesire o secure by Letters Patent is 1. In a device o the combination Igether at their meeting edges, a link carried by one of the blades, andmeans for adthe character described,

, iixilsjtxably connecting the other blade "to the at -various"\p oints-a'lon g the length thereof. e

2. In a device of the character described,

the combination with two pivoted blades "f two blades hinged to-' hingedtogether at one end and provided with cuttin edges adjacent to the hin'ed end, of hen es carried by the opposite edge of the blade, a linkpivoted to one blade and having fa series of holes therein connected byas ot, and a locking pin mounted on the other blade and having a bodyportionlarger than the slot, and a stem-portion smaller than the slot,and means for nor mally holding the body portion of the pin in the holesin the link.
